Everything you need to know about Covid-19 vaccines Which can be found by the authors. But, for the ones we can't find any information which actually we're all fascinated in, like Sputnik or the Chinese vaccines, or the Cuban vaccine, bupkes.

Oddly, nothing about Johnson & Johnson, the only single dose design I know about.

Absence of information leads to presence of .. assumptions. Like, "they're all bad" which is far from the truth: They have different qualities of test, but they're not nothing.

Also no mention of Covax, or the sub-strains of the Oxford Vaccine now made by CSL in Australia, but (regrettably) not yet recognized by many EU economies as a "valid" treatment despite being immunologically identical to the sources used in Europe. This kind of petty beaurocracy is causing real pain to individuals seeking to travel.

Also, nothing about vaccine mixtures. And, a lack of clarity about the emerging need of a third topup. Vaccine mixtures might elucidate a stronger response than just AZ twice (for instance) so this could mean MORE people getting higher immunity, if a mixture was used.
